Thanks to top reviews!

A great route taking in a multitude of terrain. Plenty of space throughout for overtaking. Brilliant support around the course. Dave M

I've been running it regularly for nearly 10 years in all conditions and it's nearly impossible to find fault. Ben K

Well organised as usual. Great conditions this time. The D-Day Museum was a really good base for a bag drop, and had a good café. Brett R

Well run event... Nice route with tarmac, gravel and the seemingly infamous ‘muddy beach’ section gives a great variety! Flat course in general and different! Great medal - if you’re after that achievement bling! All in all, highly recommend anyone to take part, all abilities and great for beginners to get use to the distance. Todd P

A beautiful race! Easy sign up process and good value for money plus brilliant pre-race communication with plenty of updates before the date of the event. Claire T

Very smooth organisation, a nice medal and good post-race snacks. Communication before the day was regular and excellent. Easy to access and plenty of parking nearby. A mostly flat course taking in coastal paths, promenades, a beach and parks. A small interesting muddy beach to cross and beautiful views out across the harbour, especially on a sunny morning.
